Climate & Earth Science
NERSC users have made significant and long-lasting improvements to the scientific basis for assessing the potential consequences of climatic changes and costs of alternative response options. Efforts using higher resolution, improved physical, chemical, and biological process representations, and more precise uncertainty estimates continue to explore potential ecological, social, and economic implications of climatic change.
In addition, NERSC researchers work in a variety of Earth modeling activities, including geophysical and molecular dynamics representations of the Earth's composition; studying processes involved in using geophysical reservoirs to extract and store carbon dioxide so as to eliminate greenhouse gas from the atmosphere; and detailed examination of clay-mineral interfaces. These wide ranging investigations have a common emphasis on supporting DOE's science mission by providing basic research to underpin the nation’s strategy for understanding and mitigating the terrestrial impacts of energy technologies.
Representative examples of research in these vital areas appear below.
First-ever study of its kind produces counter-intuitive result but solid explanation. Read More »
Carbon sequestration is a geoengineering technique suggested as a possible mitigation strategy for global warming. A new adaptive mesh refinement (AMR) technique developed at NERSC improves simulation accuracy and allows researchers to capture complex, long-term behavior that cannot be deduced in 2-D simulations.

NCAR scientists continue to perform fundamental research into understanding processes that influence the natural variability of the earth’s climate system, and relate those processes to possible future manifestations of anthropogenic climate change. Read More »
This project uses an Ensemble Kalman filter to reconstruct global weather conditions in six-hour intervals from 1871 to the present. The aim is to validate tools for future projections by successfully recreating -- and explaining -- climate anomalies of the past. Read More »
